The unified Future Reality Lab library for XR systems in Unity.
Either download and unpack the .zip, or clone this repo directly into the Assets folder of your Unity project.
cd ./Assets/
git clone https://github.com/futurerealitylab/FRL.XR.gitPLEASE SEE TEMPORARY HOTFIX BELOW.
Drag the XRPlayer prefab into your scene. Then, look at the XRManager Component:
There are four supported SDKs: Wave, OVR, SteamVR, and Daydream. Windows Mixed Reality is technically supported without an SDK, but requires Windows 10 Fall Creators edition. Select the SDKs you plan on using. There will be compilation errors if you select an SDK and don't have it installed in your Unity project. Once you've selected the SDKs, change the System field to match the system you want to use.
Please add the following pre-compiler definitions to your project depending on which platform(s) you are developing for:
WaveVR: WAVE
OVR: OVR
SteamVR: STEAM_VR
Daydream: DAYDREAM
If you have custom models for your controllers, you can put them under the XRController GameObjects found under XRManager.
In order for a GameObject to receive input when it is being pointed at, it needs a component which implements one of the Pointer interfaces, and a Collider component.
In order for a GameObject to receive input globally (whenever any button is pressed), it needs a Receiver component and a component which implements one of the Global interfaces. If the module field of the Receiver component is populated with one of the XRControllerModule or HMDModule components found on the XRHMD and XRController GameObjects, that GameObject will only receive global input from that specific module. Otherwise, the GameObject will receive input from all input modules.
Here is an example implementation of a GameObject receiving global and pointer inputs.
using UnityEngine;
using FRL.IO;
[RequireComponent(typeof(Receiver))]
public class ExampleInput : MonoBehaviour, IPointerTriggerPressDownHandler, IGlobalTouchpadTouchHandler {
private Renderer objectRenderer;
void Awake() {
objectRenderer = GetComponent<Renderer>();
}
private void SetColor(Color color) {
Debug.Log("Setting Color to: " + color);
objectRenderer.material.color = color;
}
public void OnPointerTriggerPressDown(XREventData eventData) {
//This will only be called when the object is being pointed at by a controller.
Color color = (eventData.hand == XRHand.Left ? Color.blue : Color.red);
SetColor(color);
}
public void OnGlobalTouchpadTouch(XREventData eventData) {
//This will be called whenever any touchpad is touched.
Debug.Log("My " + eventData.hand + " hand is touching the Touchpad!");
}
}The full set of supported interfaces can be found in the FRL/IO/Interfaces/Interfaces.cs class.
This is an actively developed, open source library. Please feel free to log issues and feedback! It helps us make the library better for you.
